REENFORCING MEANS FOR CONTAINERS.

Application filed October 4, 1926. Serialv No. 139,322.

Thi's';jinvention'relates to improvements in reenfoi'cing means for containers and its purpose is to provide an improved annular band or rim which may be employed In connection with butter tubs, baskets and the like, for the purpose of reenforcing them and retaining the parts thereof in assembledrelat on. The principal purpose of the lnvention 1s to provide a reenforcing band or rim having an 1mproved joint for uniting the meeting ends thereof.

Heretofore, butter tubsand other contain- 'ers have been provided with metallic bands or hoops, but these members have been obj ectionable because, of the means employed for uniting the ends thereof, it having been the practice to overlap the ends and rivet or otherwise secure them together without making any provision for the interfitting of beads or flanges or other projecting parts carried by the bands. The principal object of the present invention is to provide a band having a joint in which the cooperating parts of the meeting ends of the band are arranged to mterfit with each other in order to provide a smooth joint, thereby preventing in ury to the hands of workmen during the packlng and shipment of the containers. A further object is to provide an improved annular band provided with a bead and an inwardly directed flange overlapping each other at their meeting ends and arranged to interht with each other to eliminate projecting edges, in combination with means for securing the overlapping ends together. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanyingdrawings in wh ch -certain embodiments of the invention are illustrated. In the drawings, Fig. 1 shows a perspective view of a butter tub provided with a rim and hoops or other bands embodying the features of the present invention; Fig. 2 is an enlarged detail vertical section taken on the line22 of Fig. 1; Fig. 3 is an enlarged detail section taken on the line 33 of Fig. 1; Fig.4 is a perspective view of the meeting ends of the improved band when separated from each other, showing the arrangemen't of the interfitting parts of the joint; Fi 5 is a perspective view of a modification lowing the adaptation of the ining the separated ends of a modified band adapted for use as a hoop'around a tub or the like.

In Fig. 1 of the drawings there is illustrated a butter tub 10 made up of a plurality of staves 11 which form the outer annular wall, these staves being maintained in assembled relation to each other and the bottom of the tub by means of three annular hoops 12. The top cover 14 of the tub is provided with an annular rim 15 arranged to extend downwardly around the outer edges of the staves 11, as shown particularly in Fig. 2.

The rim 15 embodying the features of the present invention is formed of sheet-metal and comprises an annular band or strap 15 having formed along the upper edge thereof an inwardly directed corrugated flange 15" which is preferably countersunk in the woodon cover 14, as shown at 16, according to the usual practice, so thatthe upper surface of the flange lies substantially flush with or below the top surface of the cover 14. The portion 15 of the band is provided along its lower edge with a bead 15, the bead and the flange 15 being formed in suitable rolls or the like, whereby the completed reenforcing rim may be readily formed from a strip of sheet--metal of predetermined length. The body portion 15-0I' the band is preferably corrugated at shown at 15, the corrugations being tapered from the flange toward the head. The edges of the wooden cover 14 are preferably beveled asshown at 17 and the flange 15 is directed at such an angle to the body portion 15 that the parts fit closely on the surfaces of the cover, as shown in Fig. 2, and permit the part 15 to extend downwardly around the upper ends. of the staves 11.

In order to join the ends of the band without causing the projection of sharp edges or other parts which would injure the hands of the users, the bands are joined in the novel manner illustrated particularly in Figs. 3 and 4. As there illustrated, one end of the. band 15 has the bead 15 thereof cut away as shown at 18, the lengthof the cut-awa portion being equal to the length of over ap of the ends of the band. The other overlapping end of the band has the inwardly directed corrugated flange 15 thereof cut away as Lil shown at 19, for a distance corresponding to the length of overlap of the ends, so that when the two ends are overlapped one end 20 of the bead engages closely the other end 21 of the bead and, similarly, one end 22 of.

the flange engages closely the other end 23 of the flange and the outer surfaces of these parts lie substantially flush with each other so that the fingers of the users may pass thereover without interference or injury. The projectingror overlapping ends of the bands are provided with apertures 24 which, when the parts have been overlapped, are secured together by rivets 25, thereby forming a rigid and continuous annular band. When the parts are formed in the manner described, the edge 26 of the band at the point where the bead is cut away, fits within the bead adjacent'the other end of the annular head,

and theedge 27 of the band 15* fits inside of the flange 15 on the opposite end of the band so that the edges of the part 15 at the point where the joint is made are entirely protected by other parts of the rim.

In- Fig. 5, there is illustrated the adapta tion of the invention to a band 13 which is adapted to be passed around the bottom of a basket or other container. The band 13 is preferably uncorrugated but is provided with an inwardly extending corrugated flange 13 which is adapted to engage the outer edge of the bottom of the basket. In joining the ends of this band, the flange 13 is cut away at one end for a distance corresponding togghe length of overlap, thus permitting the ends of the flange 13 to lie in the same plane without any projecting edges, the parts are then secured together by means of rivets 28, forming a substantially smooth joint.

In Fig. 6 of the drawings there is illustrated the adaptation of the invention to the reen forcing hoops 12 which are passed around intermediate parts of the tub or other container. The bands 12 may or may not be corrugated, but are prot'ided preferably along their lower edges with annular beads 12 which are formed by rolling the edges of the metal from which the bands are formed. The bands 12 may be slightly flared to correspond to the flare of the walls of the tub and the end ofv the bead 12 is cut away as shown at 29 so that the projecting end 12 of the strap will fit within the bead at the other end of the vided along one edge with an annular bead and provided along the other edge with a laterally projecting flange, the ends of said band overlapping, said flange being cut away at one'end of the band for the length of the overlap, said bead being cut away at the other end of the band for the length of the overlap, and means for securing the overlapping ends of the annular strip together. v

2. A reenforcing annular metal band comprising a flat sheet-metal annular strip provided along one edge with an annular bead and provided along the other edge with a laterally projecting flange, the ends of said band overlapping, said flange being cut away at one end of the band for the length of the overlap, said head being cut away at the other end of .the band for the length of the overlap, said overlapping ends of said strip being provided with registering holes, and rivets engaging said registering holes.

3. A reenforcing annular metal band comprising a flat metal annular strip provided .along one edge with an annular bead and along its opposite edge with an annular laterally projecting flange, said flange being cut away at one end of said band, said bead being cut away at the other end of said band, said ends of said band being overlapped with the free edge of the band from which the flange has been cut projecting beneath the head at the other end of the band, and means for securing the overalpping ends together.

In testimony whereof, I have subscribed my name.
